Air Fryer Stuffed Peppers are sweet bell peppers filled with seasoned ground beef, tender rice, rich tomato sauce, and melted Colby Jack cheese. Cooking them in the air fryer cuts the bake time down to 12 minutes at 380°F while keeping the pepper walls tender-crisp instead of soggy. It is a fast weeknight dinner that skips the hour-long oven bake.
The first time I tested stuffed peppers in my air fryer for a Tuesday dinner with my brother, I made a big mistake. I stuffed raw bell peppers with cold filling and ran the machine for 20 minutes. The cheese burned into a hard crust while the pepper walls stayed stiff and raw.
On my next batch, I par-cooked the empty peppers for 10 minutes first while browning the beef filling on the stove. Once stuffed, they only needed 2 minutes to melt the cheese. This two-step method builds soft, sweet peppers and bubbly filling in 30 minutes flat, while using up leftover rice from your fridge.

Before You Get Started
- Pick wide, flat-bottomed peppers: Choose 4 medium-to-large bell peppers with four bumps on the base so they stand straight in the basket. In my testing, red, yellow, and orange peppers tasted sweeter and softened faster than green ones.
- Dump the hot water after par-cooking: Liquid pools inside the empty peppers during their first 10-minute air fry. I forgot to pour this bitter juice out once, and it turned the bottom rice layer into watery mush.
- Use meat with a little fat: I use 85/15 ground beef so the filling stays juicy. If you prefer poultry, use ground chicken thigh or turkey thigh instead of lean breast meat, which dries out in the skillet.
- Grate cheese from a block: Bagged shredded cheese is coated in starch that stops it from melting smoothly. Freshly grated Colby Jack melts into gooey strings right inside the warm filling.
- Keep water near the stove: Every burner heats differently. If your diced onions brown too fast before softening, splash 2 tablespoons of water into the pan to steam them and lift up the browned bits.
Ingredients
- 4 medium-to-large bell peppers (red, yellow, or orange; tops cut off and seeded)
- 1 ¼ cups (140g) Colby Jack cheese, freshly grated and divided (1 cup for the filling, 4 tablespoons for topping)
- 1 tablespoon olive oil
- 1 medium yellow onion (about 200g), finely diced
- 1 pound (450g) ground beef (80/20 or 85/15 lean-to-fat ratio)
- 3 cloves garlic, minced or pressed
- 1 teaspoon dried Italian seasoning (or ½ teaspoon dried thyme plus ½ teaspoon dried oregano)
- ¾ teaspoon fine sea salt
- ¼ teaspoon freshly cracked black pepper
- ¼ teaspoon red pepper flakes (optional, for mild heat)
- 1 can (15 ounces) diced tomatoes, undrained
- 1 can (8 ounces) tomato sauce
- 2 cups cooked white or brown rice (chilled leftover rice works best)
Instructions
Step 1: Prep and Par-Cook the Bell Peppers
First, preheat your air fryer to 380°F (193°C). Slice the tops off all 4 bell peppers and use a metal spoon to scoop out the seeds and white ribs cleanly. (In my kitchen, I always test each pepper on the cutting board and shave a thin slice off any wobbly bottom so it stands flat without poking a hole in the base.)
Next, stand the 4 empty peppers upright inside the preheated air fryer basket. Air fry at 380°F for 10 minutes until the walls soften slightly and the skin looks lightly blistered. Remove the peppers with tongs and tip each one over the sink to pour out the bitter hot water pooled inside.
Step 2: Sauté the Diced Onions
Meanwhile, heat 1 tablespoon of olive oil in a large 12-inch skillet over medium-high heat until shimmering. Add 200g of diced onion and stir well to coat every piece evenly in oil.
Cook the onions for 5 minutes, stirring every minute, until soft and translucent around the edges. (I learned the hard way that getting distracted by my phone leads to scorched onions, so I splash 2 tablespoons of water into the pan whenever the edges darken too fast.)
Step 3: Brown the Ground Beef and Aromatics
Once the onions are soft, add 1 pound of ground beef straight into the hot skillet. Press the 3 garlic cloves directly over the meat, then add 1 teaspoon of Italian seasoning, ¾ teaspoon of salt, ¼ teaspoon of black pepper, and ¼ teaspoon of red pepper flakes if using.
Break the meat apart into small crumbles with a wooden spoon. Cook over medium-high heat for 4 minutes, stirring often, until no pink spots remain and the pan smells richly of garlic and toasted herbs.
Step 4: Simmer and Thicken the Tomato Sauce
Next, pour the 15-ounce can of diced tomatoes with their juices and the 8-ounce can of tomato sauce into the browned beef. Stir well and bring the mixture to a steady bubble.
Simmer over medium heat for 5 minutes, stirring occasionally, to boil off excess tomato water. You will know the sauce is thick enough when you drag your spoon through the center of the pan and it leaves a clear path for 2 seconds before filling back in.
Step 5: Fold in the Cooked Rice and Cheese
After the sauce thickens, take the skillet off the burner and let it cool for 1 minute so the cheese does not separate into oil. Add the 2 cups of cooked rice and 1 cup of grated Colby Jack cheese to the warm pan.
Fold everything together gently with a spatula until the rice is coated in red sauce and the cheese pulls into stretchy strings. Taste a spoonful of the filling now and add a pinch of salt if needed.
Step 6: Stuff the Peppers and Melt the Cheese
Finally, spoon about 1 cup of warm filling into each par-cooked bell pepper, piling it right up to the rim. Tap the base of each pepper gently on the counter twice so the filling settles into the bottom corners with no air gaps.
Top each pepper with 1 tablespoon of the remaining Colby Jack cheese and set them back inside the air fryer basket. Cook at 380°F for 2 minutes until the cheese melts and bubbles around the edges, then serve hot.
How To Make
- Preheat and core: Heat your air fryer to 380°F, slice the tops off 4 bell peppers, and scoop out the seeds and ribs with a spoon.
- Par-cook the shells: Air fry the empty peppers at 380°F for 10 minutes until tender, then tip them over the sink to drain the liquid inside.
- Soften the onions: Sauté 200g of diced onion in 1 tablespoon of olive oil over medium-high heat for 5 minutes until translucent.
- Brown the beef: Add 1 pound of ground beef, 3 pressed garlic cloves, Italian seasoning, salt, and pepper, cooking for 4 minutes until browned.
- Reduce the sauce: Stir in 15 ounces of diced tomatoes and 8 ounces of tomato sauce, then simmer for 5 minutes until thick.
- Fold the filling: Take the pan off the heat, wait 1 minute, and fold in 2 cups of cooked rice and 1 cup of shredded Colby Jack cheese.
- Stuff and melt: Spoon 1 cup of filling into each pepper, top with 1 tablespoon of cheese, and air fry at 380°F for 2 minutes.
Tips for Best Results
- Use the spoon-drag test for the sauce: In my early batches, I stopped simmering the tomatoes after 2 minutes, and thin sauce leaked into the air fryer drawer. Always simmer the full 5 minutes until your spoon leaves a clear trail across the skillet floor.
- Reach for cold, day-old rice: Freshly cooked hot rice is soft and soaks up too much liquid, turning mushy in the pan. I found that cold leftover rice stays firm and gives each bite better texture.
- Save the extra filling for easy lunches: Including 2 cups of rice makes about 1.5 cups of bonus filling after stuffing 4 medium peppers. I eat a bowl of it warm on its own or spoon it over tortilla chips for quick nachos.
- Swap in large tomatoes for pepper haters: When cooking for family members who dislike bell peppers, I hollow out firm beefsteak tomatoes instead and skip the initial 10-minute air fry.

| Original Ingredient | Best Tested Substitute | Effect on Taste & Texture |
| 85/15 Ground Beef | Ground chicken thigh or turkey thigh | Milder flavor; stays juicy unlike dry breast meat. |
| 4 Bell Peppers | 4 large firm beefsteak tomatoes | Sweeter and juicier; skip the 10-minute par-cook step. |
| Colby Jack Cheese | Sharp Cheddar or Monterey Jack | Cheddar adds sharp tang; Monterey Jack melts extra smooth. |
| 1 tsp Italian Seasoning | 1 tsp curry powder + ¼ cup golden raisins | Creates a warm, sweet-and-savory spiced meat filling. |
| 2 Cups Cooked Rice | Omit rice completely | Lowers carbs and fills 4 peppers with zero leftover filling. |
Storage & Reheating
- Fridge Storage: Cool leftover Air Fryer Stuffed Peppers to room temperature, then store them upright in an airtight glass container in the fridge for up to 4 days.
- Freezer Storage: Wrap cooled peppers individually in plastic wrap, seal them inside a freezer bag, and freeze for up to 3 months. Thaw overnight in the fridge before reheating.
- Air Fryer Reheating: Place chilled stuffed peppers in the air fryer basket at 350°F for 4 to 5 minutes until the center hits 165°F. Loosely tent the tops with foil if the cheese browns early.
FAQs
Do you have to boil bell peppers before air frying them?
No, you do not need to boil bell peppers before air frying them. Air frying the empty, hollowed-out peppers at 380°F for 10 minutes softens the walls faster than boiling a pot of water. It also blisters the skin slightly, which brings out the natural sweetness of the pepper without waterlogging it.
Can I put raw ground beef in stuffed peppers in the air fryer?
You should not put raw ground beef inside stuffed peppers for the air fryer. Because the air fryer circulates intense heat fast, the top layer of cheese and pepper edges will burn before raw meat in the center reaches a safe 160°F. Always brown the beef in a skillet first.
Why are my air fryer stuffed peppers watery at the bottom?
Stuffed peppers turn watery when natural moisture cooks out of the pepper walls and pools in the bottom cavity, or when the tomato sauce is not reduced enough. Always pour out the liquid inside the peppers after their 10-minute par-cook, and simmer the skillet sauce for 5 minutes until thick.
Can I make air fryer stuffed peppers without rice?
Yes, you can easily leave out the 2 cups of cooked rice for a lower-carb dinner. In this recipe, the beef, onion, tomato, and cheese mixture alone yields about 4 cups of filling, which is the exact amount needed to fill 4 medium bell peppers to the top.
How many stuffed peppers fit in an air fryer at once?
Most standard 5-quart to 6-quart basket air fryers comfortably hold 4 medium-to-large bell peppers standing upright at one time. Leave about half an inch of space between each pepper so hot air can circulate around the sides and cook the walls evenly in 10 minutes.
